Patent number: 6030124Abstract: A linear rolling bearing comprising a fixed guide rail (1) and a guide carriage which has a U-shaped cross-section and partially surrounds the guide rail (1), said guide carriage being slidably mounted on the guide rail (1) while being constituted by a carrier body (2) on whose ends pointing in directions of movement, there are arranged head pieces acting as deflectors for rolling elements and comprising end wipers in contact with the guide rail contour, longitudinal wipers (13) which act as seals and have sealing lips (19) which bear against the guide rail (1) being arranged between the guide carriage and the guide rail (1). According to the invention, an additional sealing lip (20) is formed on each longitudinal wiper (13) and bears against the carrier body (2).Type: GrantFiled: October 11, 1998Date of Patent: February 29, 2000Assignee: INA Walzlager Schaeffler oHGInventors: Ralf Moseberg, Frank Scheib, Annette Welsch

Patent number: 5988884Abstract: A guide rail arrangement for connecting two relatively displaceable components comprising a lower rail (1) and an upper rail (2) supported thereon by rolling elements (3), said lower and upper rails being configured as rectilinear sheet metal profiles, one of the lower and upper rails partially surrounding the other of the lower and upper rails, whereby hollow spaces are formed for receiving the rolling elements (3) and further slide elements (4) arranged between the rails is characterized in that, in a central region of the arrangement, the two rails (1, 2) define a receiving space (5) for a spring and/or damping element, which receiving space (5) is adjoined by regions comprising the rolling elements and the slide elements (4) and extending in end regions of the rails (1, 2) which results in the creation of an arrangement with uniform load distribution on its components so that a deformation of the components and a pressing-in of the rolling elements is reliably prevented.Type: GrantFiled: December 3, 1997Date of Patent: November 23, 1999Assignee: INA Walzlager Schaeffler KGInventors: Frank Scheib, Klaus Baalmann, Jorg Gwosdek, Ralf Moseberg, Thomas Winkler, Barbara Fess, Thomas Kurz, Rainer Kleber, Joecbim Ritter, Rolf Fleischhauer
